Pseudotumor Cerebri

Pseudotumor cerebri (PTC), also known as idiopathic intracranial hypertension (IIH), is a disorder in which the pressure inside the skull (intracranial pressure) is abnormally high. This pressure can cause swelling of the optic nerve, which can lead to vision loss.

The symptoms of PTC can vary from person to person, but they may include:

• Headache

• Blurred vision

• Double vision

• Visual field defects

• Neck pain

• Ringing in the ears (tinnitus)

• Nausea and vomiting

• Fatigue

If you have questions about pseudotumor cerebri, it is important to seek care with an eye care professional.
